Many paleoclimate researchers pick foraminifera out of sediment to identify the species and measure the chemistry of foram shells. Here are just a few species of foraminifera that we find in our samples. The species of forams in sediment can tell us about the age of the sediment, the temperature of the Earth when the sediment was deposited, even the sea level when the foram was alive! Some forams swim around the water column, close to the water’s surface, while others live on or near the ocean floor.
Planktic – (planktonic) something that floats/swims in the upper water column
Benthic – (benthonic) something that lives on or near the ocean/lake floor
